Manuel Bastioni LAB characters are rendered pink/purple on different machines
From here I found that the missing textures should be assigned again. So selected 

Blender-&gt; File -&gt; External Data -&gt; Find missing files 

and then went to the folder

/Applications/Blender.app/Contents/Resources/2.79/scripts/addons/manuelbastionilab/data/textures/

The issue was solved. Now to avoid this happening again you select select the Blender-&gt; File -&gt; External Data -&gt; Pack all into .blend so the textures will be integrated into the .bled file and don't have to be loaded from original texture folder every time.
